Aeroacoustics#
In this notebook we showcase how to set up and run an aeroacoustic simulation for a quadcopter using the Flow360 Python API. The process involves creating a project, defining multiple simulation runs by forking cases, and retrieving aeroacoustic results.
1. Setup and Imports#
We begin by importing libraries and modules. flow360 is the main package, and pandas is used for data handling of the results.
[1]:
import pandas as pd
import flow360 as fl
from flow360.examples import Quadcopter
2. Project Creation#
A Flow360 Project is a container for simulation assets such as geometries, meshes and cases. Here, the project is initialized from a pre-existing volume mesh file.
[2]:
Quadcopter.get_files()
project = fl.Project.from_volume_mesh(
Quadcopter.mesh_filename, name="Aeroacoustic results from Python"
)
vm = project.volume_mesh
[12:38:50] INFO: VolumeMesh successfully submitted: type = Volume Mesh name = Aeroacoustic results from Python id = vm-a4b4e3cf-ef87-434b-9244-ef9753752cf1 status = uploaded
3. Simulation Parameters#
This section defines the simulation parameters. This includes defining the rotating zones, unsteady time-stepping parameters, and the physical models for the simulation.
Rotation Zones#
Provided volume mesh contains four separate rotating zones, one for each rotor. These zones need to have their center of rotation and axis specified. The rotational speed omega is also defined.
[3]:
with fl.SI_unit_system:
rotation_zone_1 = vm["zone_r1"]
rotation_zone_1.center = [-0.125, 0.125, 0.0055]
rotation_zone_1.axis = [0, 0, 1]
rotation_zone_2 = vm["zone_r2"]
rotation_zone_2.center = [-0.125, -0.125, 0.0055]
rotation_zone_2.axis = [0, 0, -1]
rotation_zone_3 = vm["zone_r3"]
rotation_zone_3.center = [0.125, -0.125, 0.0055]
rotation_zone_3.axis = [0, 0, 1]
rotation_zone_4 = vm["zone_r4"]
rotation_zone_4.center = [0.125, 0.125, 0.0055]
rotation_zone_4.axis = [0, 0, -1]
omega = 6000 * fl.u.rpm
[12:39:30] INFO: using: SI unit system for unit inference.
Time Stepping#
For this unsteady simulation, the time step size and total number of steps are determined based on a desired rotational increment per step and the total number of rotor revolutions to be simulated. We will start with 3° of rotation per time step for 5 revolutions.
[4]:
with fl.SI_unit_system:
# Time step size is calculated based on a specified rotation per time step.
deg_per_time_step_0 = 3.0 * fl.u.deg
time_step_0 = deg_per_time_step_0 / omega.to("deg/s")
# Total number of steps is determined by the required number of revolutions.
revolution_time_0 = 360 * fl.u.deg / omega.to("deg/s")
steps_0 = int(5 * revolution_time_0 / time_step_0)
INFO: using: SI unit system for unit inference.
Simulation Parameters Object#
The SimulationParams object gathers all settings for a simulation run, including reference geometry dimensions, operating conditions, solver settings, and boundary conditions. Previously specified rotation zones will be assigned to a Rotation model.

4. Executing the Simulation and Forking#
The simulation is executed in stages. As can be seen based on the settings up above, our first run will be a coarse, first-order simulation in order to establish an initial flow field. Subsequent simulations are then ‘forked’ from previous ones. Forking a case initializes a new simulation from the results of an existing one, which can significantly reduce computational cost when iterating on simulation parameters. This is particularly useful for changing numerical schemes or introducing new outputs without restarting the simulation from scratch.
Note: First order run is not required here, but is used for demonstration purposes nonetheless.

Second Run with Higher Order Accuracy#
For the second run, the order of accuracy for the solvers is increased to 2, and the time step is refined. The case is forked from the initial run to leverage the already computed flow field.
[7]:
# For the second run, parameters are updated directly on the params object of the completed case.
# The order of accuracy is increased and the time step size is refined.

Final Run with Aeroacoustic Outputs#
The final simulation is forked from the second-order run. AeroAcousticOutput is added to the simulation parameters to collect acoustic data from specified observer points.
